Exhale is a small UK brand making alcohol-free beers with a twist: each one is infused with a functional mushroom chosen for its supposed wellness properties. Roar uses Lion's Mane, a mushroom associated with cognitive support, brewed into a pale IPA at 0.5% ABV. Whether you feel the nootropic effects is between you and your brain chemistry, but as a beer it's a perfectly legitimate thing to crack open. The pour is light amber with a short-lived frothy head. On the nose there's a clean hop character — citrus and a touch of floral — without the more aggressive resinous notes you'd expect from a mainstream IPA. The taste delivers on the citrus promise, though the overall profile sits on the lighter side of the style. Some reviewers find it a bit subdued; it's more a functional beverage that happens to taste like beer than a full flavour workout. The chilli in the ingredients list is subtle at best. It's vegan and gluten-free despite containing malted barley and wheat — the brewing and filtration process brings it within gluten-free thresholds. Comes in a 330ml can and is available direct from Exhale and through specialist AF retailers. At around £3.50–£4.00 a can it sits at the premium end for something this light, but if the Lion's Mane angle appeals, there's nothing quite like it.
